An article at The Next Web points out that the latest marketshare numbers put Apple at the top of "PC" makers, and that some PC makers that don't have any tablet momentum are calling foul. It's "controversial" to count tablets as PCs, they say. The article points out various justifications for not categorizing tablets as personal computers, and then shoots them down. I must say, I find the argument compelling.

Yep, the smartphone/PC lines will blur more as they add wireless connectivity to external screens and more cloud storage for sharing documents. Hmmm, come to think of it, that's already showing up. It's another PC that happens to have phone functionality, but it's certainly as functional as a desktop machine from not too many years ago.

The funny thing is that price certainly doesn't define PC either - there are desktop/laptop machines that cost less than smartphones, so it's not like that provides a guide either.
